LEXAN™ Copolymer EXL1444

LEXAN EXL1444 is based on Polycarbonate (PC) siloxane copolymer resin. It is a medium flow, FDA compliant and opaque injection molding (IM) grade. This resin offers extreme low temperature (-40°C) ductility, exhibits excellent processability and release with opportunities for shorter IM cycle times compared to standard PC. This product is available in a wide range of opaque colors.
